@charlietag, it is actually still the issue, i’ve just tried.

But I found a work around which allows you to update the fileutils gem (a default gem) to the latest version and get rid of the warning by using --default option when you update the gem.

gem update --default

hope it helps.

Cheers

@foxmuldercp I have the same issue. I think it’s ruby 2.5 issue. fileutils move to gem. originally it’s under ruby stdlib.

$ gem list |grep fileutils
fileutils (1.1.0, default: 1.0.2)

$ gem uninstall fileutils

$ gem list |grep fileutils
fileutils (default: 1.0.2)

will fix this issue. But I would like my gem update to latest version.

Anyone has any idea??

Or… the best solution is using ruby 2.4.1…?

@charveasna You’re right… issue still exists… no matter how I install ruby 2.5.1…

Your Rails version is quite old, Ruby 2.5 support Rails 4.2.8+, the current stable is Rails 5.2. upgrade it with gem upgrade rails
